Proof step 922 from proof overwrite-write-page-clean (previous step)

files[ino0] = mkfile(m4, md1, m5, content1), files[ino] = mkfile(m2, md0, m3, content0), ino0 ∈ files, ino ∈ files ⊦ m ∈ content1 ⊕ mkcontent(ino0, pcache) ↔ m ∈ content1 ⊕ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(false, buf)]), ino0 = ino, ino ∈ icache, ino0 ∈ icache

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 923:
⊦ n ∈ content0 ⊕ content1 ↔ n ∈ content0 ∨ n ∈ content1
Proof step 924:
files[ino] = mkfile(m2, md0, m3, content0), files[ino0] = mkfile(m4, md1, m5, content1), ino ∈ files, ino0 ∈ files ⊦ m ∈ content1 ⊕ mkcontent(ino0, pcache) ↔ m ∈ content1 ∨ m ∈ mkcontent(ino0, pcache[datakey(ino, m), mkpentry(false, buf)]), ino0 = ino, ino0 ∈ icache, ino ∈ icache

Rule argument
